In spring, tree pollen becomes stronger. Birch trees are a major source in April and May. Oak, ash, and pine may also release pollen around this time. Days are longer, and many plants grow new leaves and flowers.

In early summer, grass pollen is common. It often starts in May and lasts through July. Ryegrass and other meadow grasses release pollen on warm, dry days. Fields, roadsides, and gardens can all have more pollen in the air.

In late summer and early autumn, weed pollen can appear. Plants like nettles and dock may release pollen from July into September. Their pollen season is usually shorter than tree or grass seasons. By October, pollen levels often drop as the weather cools.
